Oh, those are very cute! You're definitely getting the hang of it. :-)

After you fold the ribbon into the petal shapes, it helps to fold the bottom part of the petal (the part that you're going to put on the needle) in half and then fold the ends back down over itself and then putting all the layers of each petal onto the needle. That's what gives you a nice crease in the middle of each petal. I wish I could explain it better. I'm terrible at explaining things.
